The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time. The total entropy of a system and its surroundings can remain constant in ideal cases where the system is in thermodynamic equilibrium, or is undergoing a (fictive) reversible process. In all processes that occur, including spontaneous processes,[1] the total entropy of the system and its surroundings increases and the process is irreversible in the thermodynamic sense. The increase in entropy accounts for the irreversibility of natural processes, and the asymmetry between future and past.[2]

Yesterday was an ideal case where the total entropy of Lake Michigan was in thermodynamic equilibrium.  The temperatures shown on the Atwater Buoy, the itch-o-meter and the duck-o-meter were in alignment - the entropy of the isolated system remained constant.  Ah, but it was undergoing a reversible process!  The overall irreversibly of the natural processes has taken over now, entropy is increasing again (total entropy of an isolated system can never decrease over time) resulting in a restored asymmetry between future and past!  

Nevertheless, even though we were not basking in the same warm temperatures as the Atwater Buoy today, Klode was two degrees warmer than yesterday!  This kind of asymmetry between future and past is what we like.  There is less enthusiasm for future and past asymmetry when the polarity is reversed.

Itch's  toast today probably sums up how most people are reacting to this blog post - "Whatever!"

This less than inspiring toast caught Magic Mike by surprise.  He was holding his filled shot glass, looking down and speaking softly with Willa and was caught off guard.  "That was it?  I could have come up with something more inspiring than that!"  Ah, but as a student of literature, Mr. Mike surely knows that: "the moving finger writes, and having writ, moves on".  Mr. Bubble attempts to create a consensus for a do-over.  But alas, he has forgotten the rest of that quote from the Rubáiyát of Omar Khayyám; "Nor all thy Piety nor Wit, Shall lure it back to cancel half a Line, Nor all thy Tears wash out a Word of it".  There are no do-overs in real life.  

Go Cap'n and Forger at IMWI today!

  • Cap'n has finished the swim and bike and as of 4:49 pm was reported to be 9.8 miles in to the run.  Predicting he'll finish the run at 7:35 pm, which would be 12:37 for the race.
  • Forger has finished the swim and had just finished the bike at 4:44 pm.  He's just started the run so there's no estimate yet on when he'll finish.  

Hope I didn't miss anyone else who's racing today.

Either above, or maybe someone swam out the Atwater bouy and pissed on it just to screw with you?

Mr. Bubble said...

"Someone?". Someone you know perhaps? Someone who has a SUP board and could stand over the buoy and give it a Golden Shower?

Forger said...

Mr Bubble,
Thank you for the word of confidence "when" and not "if" he will finish. I can tell you all the KRU was with me through the 2.4 mile swim. I'm not a strong swimmer, the wind was blowing and water rough. For a 1600 meter stretch we headed straight into the chop. How does a not so strong swimmer get through? One stoke at a time, breath and Confidence you can only obtain via swimming with Klode Kru in Lake Michigan!
O, and yes Forger finished. Not a stellar finish, but a finish.

Hear hear about swimming with the Kru, Forger. I became more motivated to swim with the Kru after DNFing a swim at the Door County Tri. Now, I finish close to last, but I finish and I enjoy it
